After leaving the car parked outside overnight it always shakes and runs rough when i start it. When i start driving and the car warms up it idles much better even tho it still doesnt idle perfectly smooth. What could the problem ? Did the walnust blasting and new plugs installed couple weeks ago.

Not necessarily the programming. Mine makes the vanos tick until the a good 10 minutes its warmed up a bit. Might need new plugs/coils. I replaced my plugs and it helped a little bit but I should have done coils as well.

Did you get the PPK or even get the MHD programming off of google play? Might also want to look at the 1addicts forum as well. MaxBimmer is mostly geared towards to older gen BMWs. You can get any info or DIY off n54addicts/1addicts web forum. (Sorry for posting those names, remove if needed admins).

I believe this is the service bulletin for it... BMW North America any ways, run this by BMW Toronto and see...

I know when they started showing HPFF issues and the US issued extended warranty and Canada had not they fought for it and got it, not sure if injectors ever worked into that (should have obviously). I suggest calling 2-3 dealers and asking.

Alright based on my call to one of the better mechanics at BMW here (close friend) no recall on injectors for 2008, however they were replacing them under warranty if they came in and knew via the injector part number if they were the "bad" ones. Again though, no recall
